WALL STRUCTURE FOR CORN-CRIBS AND THE LIKE.

To all whom it may concern:

Be it known that I, JOHN H. IREY, a citizen of the United States,residing at West Liberty, in the county of Muscatine and State of Iowa,have invented certain new and useful Improvements in Wall Structures forCorn-Cribs and the like, of which the following is a specification.

The invention has for an object to enable the construction of ventilatedwalls such as are required for corn cribs by the use of stock material.such as is employed in the construction of concrete silos, and otherwall constructions. It is a particular object to enable the constructionof a corn crib with suitably ventilated walls, while at the same timethere will be a minimum liability of ingress of water during storms.

A further object is to provide an improve ment in a specific article ofmanufacture adapted to enable the construction of ventilated walls fromordinary blocks, bricks and the like without requiring the cutting ofthe wall nor the building of special openings therein requiring adisturbance of the orderly formation of courses as ordinarily followedin the construction of a solid wall.

Additional objects, advantages and features of invention will appearfrom the construction, arrangement and combination of parts hereinafterset forth comprising one of the possible embodiments of my invention, ana proximate representation thereof being ma e in the accompanyingdrawings, wherein Figure 1 is a fragmentary elevational view of asection of a concrete corn crib wall embodying my invention,

Fig. 2 is a fragmentary vertical cross section thereof,

Fig. 3 is a detail of the ventilating spacer unit interposed between thesuperposed blocks of the wall.

Fig. 4 is a fragmentary perspective of a modification of the spacerelement.

Fig. 5 is a fragmentary end view of a spacer with more than two bars.Fig. 6 is a fragmentary horizontal section of wall showing the angularrelation between the stave units, and the relation between the masonryunits and my spacer.

There is illustrated a section of wall 10 which may be used as acorn-crib wall or as a bin wall for other uses. In order to effect theformation of ventilating openings in the wall without changing theorderly form of Specification of Letters Patent. Patent d J 21 192Application filed October 6, 1919.

Serial No. 328,740.

the courses of blocks or other building units employed, I have provideda spacer plate and guard 11, illustrated in Fig. 3 which may beset inplace upon the'upper surface of certain of the building units and otherunits superposedthereon, bywhich the latter are held spaced above thelower ones, the plate 1l thus becoming or taking the place of buildingunits or parts thereof. Preferably in the construction of grain cribs, Iuse blocks termed stave elements which for the most part are formed withoutwardly incl ned upper and lower edges 12 and 13, in Fig. 2. Thebottom and top blocks, however, are formed with horizontal edge faces atone end and sloping faces at the other. The blocks having such formationmay be termed starting and finishing blocks,and are formed in two'sizes,one being longer than the other, as indicated at 17 and 18 in Fig.

1 so that when blocks of uniform size are superposed thereon in verticalseries or coursesthey will break omts uniformlyas shown in this view. Inits preferred form,

my spacer device is constructed as shown in Fig. 3, being a stamping ofthick sheet metal or a casting, comprising head portions 19 at each endconnected by a plurality of narrow bars 20 in sufiicient number andspaced close enough together to prevent passage therebe tween of smallrodents and vermin such as m ce. The head portions 19 are provided withprojecting ears 21, at top and bottom adapted to be set in notches whichmay be formed or cut in the opposed faces of super posed stave elementsas shown in Fig. 2. This device may, of course, also be used with staveelements having horizontal upper and lower faces, or may be formed in asize corresponding to that of an ordinary brick, and interposed betweenvertically adjacent bricks in a course of a wall, as will be understoodfrom the disclosure.

In the use of this invention, the stave elements are cast in the formindicated, and if not provided with the notches 22 adapted to receivethe cars 21 at each side, they may be notched with a chisel or othersuitable tool as they are put in place. The first course of staveelements 17 and 18 alternately are put in-place and secured by a hoopelement p 11 interposed as shown in Fig. 2, and a second hoop element 23is thenengaged around the upper ends of the elements 17 and the lowerparts of the elements 24.

customarily, the stave elements used in constructing circular cribs andbins have their vertical edge portions concave atone side and convex atthe other, as shown in Fig. .6, so that they interlock to a certainextent, thus facilitating the use of my spacingplate and preventingliabilityotlateral displacement of the upper stave elements whensupported upon my plates 11. After the weight of the upper elements islargely taken up or carried by the cement between laterally adjacentstave elements.

If desired, the spacer device maybe formed shown. in Fig. 4, wherein aplate 11 is provided similar to the one first described withthe'exception. that the head portions 19 are provided at'their upper andlower parts with oppositely extended flanges 27 by which the device willbe self-supporting upon a horizontal surface, and will also support asuperposed buildingunlt thereon in such a manner that 1t Wlll IlOt fall.to one sideior the other, while a wall is in course of erection.

It has been found that with this construction a crib can be built veryquickly, less time having been required to construct a crib of a givencapacity than by the use of any other known building material withworkmen operating at ordinary speed.

With building blocks of ordinary thick ness, the sloping of thevertically adjacent faces-of the stave elements at an angle of about 45degrees to the horizontal locates the inner upper edge portion of thelower'stave unit well above the outer lower edge of the upper staveelement, (see Fig. 2) making it impossiblefor ordinary rain to beat inupon the contents of the crib. V p

In Fig. 5 there is illustrated the possibility of forming the spacerswith a greater number of connectingbars 20 corresponding to those 20before mentioned.

lVha-t is claimed is: V p

' 1. course building element for a directly ventilated wall comprisinghead portions'and connecting air admitting vermin guard partstherebetween, said head portions having parts projected above and belowsaid connecting portions.

2. A masonry course unit comprising head parts andiconnectingair'admitting vermin guard parts, said headhaving broad upper and lowerparts to afford a wide bearingon supporting and superposed masonry.

In testimony whereof I have aflixed my signature in presence of twowitnesses.
